I'd like to think you're right, but I can't see a slaughter of
FF at the polls. It's never happened. The closest shave was the exodus to Spring's Labour, but not in enough numbers as it turned out. Republicans only really move within the
FF/independent
FF-
PD-
SF Bermuda Triangle. They're a loyal and forgiving bunch who always wrestle with their consciences and win out in the end.
FF dissent will express itself in the the local and Euro elections. They probably will lose the next GE, but only to a coalition of at least 3 parties in a relatively tight result.
Anything else would be a tectonic shift in Irish politics. I don't see any major change in the attitude of Irish people that would suggest such an shift is possible.
